Salt stress injury in tomato was mitigated only in that case if plants were hardened with high concentration of SA (~10-4 M), low concentrations were ineffective. An efficient accumulation of Na+ in older leaves is a well known feature of salt stress response of tomato (Solanum lycopersicum cv. Rio fuego) but it remains largely unexplored whether young and old leaves or root tissues have distinct antioxidant status during salt stress after hardening with 10-7 M or 10-4 M SA. Determination of superoxide dismutase (SOD) and catalase (CAT) activity revealed that the SA-induced transient increases in these enzyme activities in young leaf and/or root tissues did not correlate with the salt tolerance of plants. Salt stress resulted in tenfold increase in ascorbate peroxidase (APX) activity of young leaves and significant increases in APX and glutathione reductase (GR) activities of the roots hardened with 10-4 M SA. Both total ascorbate (AsA) and glutathione pools reached the highest level in the leaves after 10-7 M SA pre-treatment but in contrast to leaves, the total pool of AsA decreased in the roots under salt stress and thus, due to low APX activity active oxygen species were scavenged by ascorbate non-enzymatically in these tissues. The increased GR activities in the roots after treatment with 10-4 M SA enabled plants to enhance the reduced glutathione (GSH) pool and maintain the redox status of AsA under high salinity, which led to increased salt tolerance.

The role of AtGST phi 9 (GSTF9) in the salt- and salicylic acid response was investigated using 2-week-old Atgstf9 and wild type (Wt) plants. Atgstf9 mutants accumulated more ascorbic acid (AsA) and glutathione (GSH) and had decreased glutathione peroxidase (GPOX) activity under control conditions. Treatment of 2-week-old seedlings with 10(-7) M salicylic acid (SA) for 48 h resulted in elevated H2O2 level and enhanced GST activity in Atgstf9 plants, 10(-5) M SA treatment enhanced the malondialdehyde and dehydroascorbate contents compared to Wt. 50 and 150 mM NaCl increased the GST activity, AsA and GSH accumulation in Atgstf9 seedlings more pronounced than in Wt plants. We found that the Atgstf9 mutants had altered redox homeostasis under control and stress conditions, in which elevated AsA and GSH levels and modified GST and GPOX activities may play significant role. The half-cell potential values calculated from the concentration of GSH and GSSG indicate that this GST isoenzyme has an important role in the salt stress response.
